CLOTH-NAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 535,581, dated March12, 1895.

Application fil d May 1, 1 894. Serial No. 509,696. (No model.)Patentedin France May 27, 1884, No. 162,320.

To all whom it may concern:

Be it known that I, N ICOLAS HENRY Gnos- SELIN, a citizen of the FrenchRepublic, residing at Sedan, France, have invented a certain new anduseful Improvement in Cloth- Napping Machines, of which the followingisa specification.

'My invention for which Letters Patent of the Republic of France wereissued May 27, [O 1884, No. 162,320, relates to that class of nappingmachines in which a series of napping rolls is carried by a revolvingdrum or head; and my invention consists of means for operating thenapping rollers, as fully set forth I 5 hereinafter and as illustratedin the accompa nying drawings, in which- Figure l is an elevation ofsufficient of a napping machine to illustrate my improvement. Fig. 2 isa plan in part section of part of the drum.

The frame I of the machine is suitably constructed to support the partshereinafter described and in bearings on said frame turns theshaft o, ofa drum A which consists of the said shaft, two heads 5, and a series ofnapping rollers T, the axles of which have their bearings in the heads5, and carry (at one or both ends of the drum) wheels 6 which may betoothed pinions as shown or they may be 0 friction wheels orpulleys.With each series of wheels 6, which I will hereinafter term the pinions,engages a loose gear B, in the form of a wheel turning about an axiswhich may be that of the drum shaft. The said gear is 3 5 a toothedgear,if the pinions are toothed pinions, or is a friction gear if thepinions are friction pinions, and it consists of a disk which, as shown,may be a flanged disk with an internally toothed flange 7, engaging theteeth of the pinions at any suitable point, as external to the latter;and constitutes a gear which drives the pinions and which may besupported in any suitable manner, but preferably turns loosely upon theshaft 22, as the 5 support.

There will be gears at one or both ends of the drum accordingly as theshafts of the napping rolls have pinions at one or both ends.

The gear or gears B, and the drum :may be drivenin any suitable manner.As shown the drum is driven from a driving belt 40, passing toa pulleyon the shaft 0, and there is a single gear B, at one end of the drum andthe flange 7, thereof is formed on the periphery to receive a drivingbelt 8, that passes to a pulley 9, upon a counter-shaft 10, which isdriven by intermediate gearing or mechanism from the shaft 2), of thedrum.

The intermediate gearing or mechanism shown, Fig. 1, consists of apulley D, on the shaft o, anda corresponding pulley E turning upon astud 12, said pulley E receiving a belt 13, passing to the other pulley;and a pinion 14; connected with the pulley E, gears with a toothed wheel15 upon the shaft 10. 6; The bearings 16, of the shaft 10 are adjustableby means of screws 17, to tighten the belt 8.

Upon one end of the shaft o, is a pulley 16, receiving the driving belt40 by means of which the shaft is turned, together with its drum, anidler pulley 17, turning alongside the driving pulley 16.

The main feature of my invention consists in driving the pinions bymeans of the loose gear having its axis concentric with that aroundwhich the drum turns, whereby I am enabled to operate the said pinionswith great certainty and precision.

The precision of movement is effected in part by securing a circularbearing for the belt 8, that drives the napping rolls upon the gear B,instead of upon the pinions at the ends of the napping rolls as issometimes done, and in part by use of the rigid gear having teethengaging toothed pinions which prevents any slip, all of the nappingrolls being thereby compelled to turn at the same rate of speed securinga very regular and uniform action iipon the fabric.

I do not here claim the means for securing varying action of the loosegear.

Without limiting myself to the precise construction and arrangement ofparts shown, I claim as my invention- In a napping machine thecombination of a drum, napping rolls carried thereby and In testimonywhereof I have signed my provided with pinions, a loose gear turningname to this specification in the presence of on an axis concentric withthat; of the drum two subscribing witnesses.
